Hoping someone can help me diagnose an A/C problem with this car. For
background, the A/C system was mostly replaced a few years ago (new
compressor, dryer), and the monovalve is reatively new as well.
My A/C no longer turns on. If I push the auto-hi or auto-low buttons, I
get no A/C and no blower. Same for the bi-level button. But if I hit
the defrost button, the blower and the A/C come on, and it blows cold
for a few minutes. If I then hit the bi-level button the fan blows, but
no A/C, but very rarely the A/C will stay on. I will occasionally get
the fan to work with with Auto Hi or Auto Low, but usually not.
Given that my car has relatively new components, is the problem most
likely the push buttons on the dash? If so, is this something I can
easily repair/replace myself? Could it be the A/C compressor switch on
the dash? Does defrost override this switch?
Hoping for some help,
